[WIP] Program and tests written for minting token

[sammanadh]

Just wrote a simple program and test case for minting token. THIS IS A DRAFT PR, NOT FOR MERGING. didn't see a draft option while creating a pr. I guess it has to be enabled or something.

[nathanleclaire]

Yea I'm sure there's some fancy Github workflow option but we usually just throw [WIP] or [nomerge] in the PR title.

[nathanleclaire]

is this what you're hitting in the tests?

yarn run v1.22.15
$ /Users/nathanleclaire/karma/node_modules/.bin/ts-mocha -p ./tsconfig.json -t 1000000 'tests/**/*.ts'

#2 looks like it should fix the above, but I get a new and exciting error now --

Error: Error loading workspace IDL for karma

    at Object.create (/Users/nathanleclaire/karma/node_modules/mocha/lib/interfaces/common.js:148:19)

looking into it...

[nathanleclaire]

ah ok so for this other error i think you need these changes --

probably anchor is confused about the rename karma -> karma_token . Anchor autogenerates a lot of stuff based on those names so you have to watch them closely

[nathanleclaire]

with that, first passing test, good times

[sammanadh]

@nathanleclaire did the test pass without you making any changes to the karmaTokan.ts test file itself?

[nathanleclaire]

@sammanadh Yea. Are you hitting a new issue?

[sammanadh]

@nathanleclaire Yeah.

  1) karma token
       Minting a new token.:
     Error: failed to send transaction: Transaction simulation failed: Attempt to load a program that does not exist

      at MethodsBuilder.rpc [as _rpcFn] (node_modules/@project-serum/anchor/src/program/namespace/rpc.ts:29:16)

Its on line 17 in karmaToken.ts test file.

    await program.methods.mintToken().accounts({
        mint: mintKeyPair.publicKey,
        tokenProgram: TOKEN_PROGRAM_ID,
        tokenAccount: associatedTokenAccount,
        authority: walletPubKey,
    }).rpc();

Currently using localnet. Have deployed the program successfully there. Don't know why I am still getting this error. Planning to work on devnet once and see if the error persists there as well.

[sammanadh]

@nathanleclaire Finally, tests are passing successfully. Somehow, I had messed up copying the program id. Stupid mistake.
